f1683aa73c board_f: Rename initdram() to dram_init()
This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

088454cde2 board_f: Drop return value from initdram()
At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.

52c411805c board_f: Drop board_type parameter from initdram()
It looks like only cm5200 and tqm8xx use this feature, so we don't really
need it in generic code. Drop it and have the users access gd->board_type
directly.

af3971f81a MIPS: make inclusion of ROM exception vectors configurable
This adds a compile time option to include code for static
exception vectors. Static exception vectors are only needed,
when the U-Boot entry point is equal to the CPU reset exception
vector address. For instance this is the case when U-Boot is
used as ROM in Qemu or booted from parallel NOR flash. When
U-Boot is booted from RAM (e.g. loaded there by SPL), the
exception vectors need to be setup dynamically, which is done
in follow-up commits.

1221ce459d treewide: replace #include <asm/errno.h> with <linux/errno.h>
Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content.  (both just wrap <asm-generic/errno.h>)

Replace all include directives for <asm/errno.h> with <linux/errno.h>.

0dfe04d6c8 MIPS: ath79: Use mach_cpu_init instead of arch_cpu_init
In order to prepare for MIPS arch code making use of arch_cpu_init in a
later patch, stop using it from ath79 SoC code & instead use the new
mach_cpu_init which is provided for this purpose.
